Has anyone had any experience with a PSP diagnosis?

After nearly 4 years of long covid symptoms, I was recently diagnosed with Progressive SupraNuclear Palsy. I'm in denial but wondering if anyone has had a similar diagnosis with positive treatment results? Not interested in taking a med that only covers up the symptoms or a trial/test run to determine what med might work. I currently am no longer driving and family pow wow said someone needs to be in the house with me (silly). Any suggestions?
